20 Claims.

This invention relates to apparatus for setting a panel in a frame andfor inserting a sealing strip inthe frame around the marginal edge ofthe panel.

More particularly the invention concerns itself with the manufacture ofvehicle body window ventilators comprising a frame and a glass ortransparent panel. The frame usually has a bottom bar and a front barwhich ordinarily extends rearwardly in an arcuate path from the frontend of the bottom bar to also form the top of the frame. The rear sideof the frame is open and the frame bars are channel-shaped in crosssection to freely receive the glass panel. The clearance space betweenthe marginal edges of the panel and the adjacent bars of the frame isweather sealed by a resilient strip extending for substantially the fulllength of the frame bars and also channel-shaped in cross section toembrace the marginal edges of the panel within the frame.

It has been the custom to set the glass panel in the frame and toinstall the weather strip by hand methods. In practice a strip ofweather sealing material preformed to the desired length is wrappedaround the side edges of the glass panel to be engaged by the frame andthe panel is manually inserted into the frame through the open rear sidethereof while the sealing strip is held in place. The arrangement issuch that the sealing strip is deformed into channel-shapedconfiguration during assembly of the panel into the frame, and is wedgedinto the clearance space provided in the channel frame bars around themarginal edges of the glass panel. This method of assembly requires aconsiderable number of man hours where ventilators are produced on alarge production basis, and is largely responsible for-the relativelyhigh cost of manufacture.

With the above in View, it is one of the objects of this invention togreatly reduce the cost of assembly of ventilators of the type noted byproviding a machine which operates automatically to insert the glasspanel in the frame, and at the same time, install the weather strip inplace. In accordance with this invention a glass panel and the frametherefor are supported in spaced relationship in a common horizontalplane with the open rear side of the frame facing the front edge of theglass panel. The glass panel is moved toward the frame while supportedin'the same plane as the frame and ultimately assumes a position withinthe frame. Prior to movement of the glass panel into the frame aflexible weatherstrip of the proper width is, ext nded across the pathof travel of the glass panel between the latter and frame in a positionto be engaged by the front edge portion of the panel as it moves towardthe frame. Thus the weather strip is folded along opposite sides of thepanel and finally is deformed to assume a channelshaped configurationwithin the channel-shaped bars of the frame to provide a seal around thepanel.

It is another object of this invention to provide means for feeding apredetermined length of weather stri transversely across the path oftravel of the panel in timed relation to movement of the panel in adirection toward the frame.

Still another object of this invention is to provide a guide engageablewith the sealing strip as it is drawn across the path of travel of theglass panel to locate the strip in a position to be engaged along a lineintermediate the opposite longitudinal edges by the front edge of thepanel as it is advanced toward the frame.

It is a further object to provide a guide supported to one side of thepath of travel of the glass panel adjacent the bottom edge of the latterand shaped to fold the strip over the bottom edge of the panel as it isadvanced in a direction toward the frame. v

There are certain types of ventilator windows having a latch operatinghandle pivotally supported at the inner side of the ventilator on theinner flange of the frame, and in many instances, it is customary toincrease the width of the inner flange at the point of pivotalconnection of the latch handle. This also necessitates correspond inglyincreasing the width of the inner flange of the weather strip duringassembly, and it is a further object of this invention to provide meansfor adjusting the guide to locate a greater width of the strip at eitherside of the plane of the glass panel depending upon whether right orleft hand ventilators are being assembled.

The foregoing as well as other objects will be made more apparent asthis description proceeds, especially when considered in connection withthe accompanying drawings, wherein:

Although the apparatus disclosed herein may be successfully used inassembling various different products, nevertheless, it is primarilyadapted -for use in the manufacture of vehicle body ventilator windows.A typical ventilator window capable of being assembled by the apparatusis shown in Figures 44 and 45 of the drawings. This ventilator windowcomprises a frame 58, a glass panel 5! and a weather sealing strip 52.The frame 50 is of one piece construction, bent or otherwise formed toprovide a bottom bar 53 and a front bar 54. It will be noted that thefront bar .54 extends rearwardl-y from the front end of the bottom bar53 along an arcuate path, and also forms the top bar or side of theframe 50.

The rear side of the frame 50 is open and the hars making up the frameare channel-shaped in cross section. The glass panel 5| is preformed tocorrespond in shape to the contour of the frame, and engages within thechannel-shaped bars of the frame. The glass panel 5| is secureiy held inthe frame by the strip 52, which is also channel-shaped in cross sectionand extends for the full length of the frame bars. In manufacture thestrip 52 is assembled in the channel of the frame 50 by the movement ofthe glass panel 51 into the channel through the open rear end of theframe. The dimensions of the parts are such that the strip 52 isactually wedged in position and acts as a weather seal around themarginal edge of the glass panel.

In accordance with orthodox practice, a latch operating handle 55 issecured to the inner flange of the frame 58, and in the presentinstance, is located at the rear end of the bottom bar 53 of the frame.In order to accommodate the operating handle 55, the width of the innerflange on the bottom bar 53 of the ventilator frame 50 is somewhatincreased as indicated by the numeral 55. As shown in Figure 45 of thedrawings the inner flange of the channel-shaped weather strip '52 isalso increased in width to correspond with the portion '56 of the frame.This particular type .of construction is illustrated because itnecessitates extending the inner side or flange of the weather stripbeyond the outer side flange during movement and provision is made inthe apparatus about to be described for accomplishing this result.

The window ventilator shown in Figure 46 of the drawings difiers fromthe one previously described in that both the inner and outer flanges ofthe bottom bar of the frame are correspondingly increased in width atthe rear end of the bar to accommodate the operating handle. With thisdesign the weather strip may be symmetrically positioned relative to themarginal edge of the glass panel during assembly, as it is not necessaryto provide a greater width of strip on one side than on the other.Attention is also called to the fact that the ventilator window shown inFigure 46 is of the left-hand type, whereas the ventilator shown inFigure 45 is of the right-hand type. With the above exceptions the twoconstructions are identical and like reference characters are used todesignate corresponding parts.

In general the apparatus comprises a glass panel supporting fixture 56,a slide or carriage 57 for the glass panel, a frame holding fixture 58,operating mechanism '58 for the sealing strip 52 and frame structure 59for supporting all of the above assemblies. As shown particularly inFigure 5 of the drawings, the holding fixture 58 for the ventilatorframe 50 is secured to the frame structure 59 adjacent the front end ofthe latter, and at the start of the cycle of operation of the apparatus,the slide '51 for the glass panel 5| is positioned on the framestructure 59 adjacent the rear end of the-latter.

It will further'be noted from Figures 1 and s of the drawings that theholding fixture 58-sup-' ports the ventilator frame 50 in a horizontalplane with the open rear end of the frame 50 facing the slide 51. Theslide 51, on the other hand, supports the glass panel in the horizontalplane of the ventilator 50 with the front edge of the panel facing therear open side of the ventilator frame and positioned to extend into theventilator frame upon movement of the slide 51 toward the fixture 58.

During initial advancement of the slide 57 toward the holding fixture58, the mechanism 59' operates to pull a length of weather stripping 52across the path of travel of the glass panel 5| between the latter andthe frame 55, as shown in Figure 2 of the drawings. The arrangement issuch that the strip 52 is engaged at approximately its longitudinalcenter line by the front edge of the glass panel 5| as the lattercontinues to advance toward the frame 50. Thus during the final movementof the slide 5'! to set the glass panel 5| into the frame 50, theweather strip 52 is folded about the adjacent marginal edges of thepanel, and is forced into the ventilator frame 50 to assume the locationpreviously described. The ventilator window assembly is then removedfrom the holding fixture, and the slide 57 returns to its initialstarting position in readiness for the next cycle of operation.

Glass panel supporting fixture The glass panel supporting fixture isbest shown in Figures 6, 13 and 14. This feature embodies a shaft 60extending transversely of the machine frame 59 adjacent the front end ofthe latter and having the opposite ends respectively journalled inbrackets 6| secured to the machine frame. Secured to the shaft 66 inspaced relationship axially of the shaft is a pair of arms 52havingslots 63 extending lengthwise of the arms from the free ends thereof.The slots 63 are of sufiicient dimension to freely receive the oppositemarginal edge portions of the glass panel 5| and serve to hold thelatter in position on the arms. The bottom walls 64 of the slots projectbeyond the opposite top walls to pro-- vide bearing surfaces for guidingthe glass panel into the slots 53. The arms 62 extend toward the frontend of the machine and are inclined in an upward direction to hold theglass panel 5| in the position thereof shown in Figure 6 of thedrawings.

The shaft 56 is rotated in a direction to swing the glass panel 5|downwardly into engagement with the operating slide 5? by a cam 65'shown.

in Figures 13 and 14 of the drawings as secured to a shaft 65. The cam65 is engaged by a follower til-supported directly below the peripheryof, the cam 65 on an arm 58 intermediate the ends of the latter. Thefollower 51 is yieldably held in contact with the periphery of the cam55 by a spring 59 having the lower end connected to'the front end of thearm 58 and having the upper end suitably anchored on the mainframe 59.The rear end of the arm 68 is pivotally connected to the frame 59 by apin 10.

-The arm 68 is also. connected to the shaft EB for'rocking the latter bya rod 12 having the lower end pivoted to the arm 68 adjacent its frontor free end and having the upper end pivoted to one end of a link 13.The opposite endof the link 13 is secured to the shaft 50 andimparts.-..a rotative. movementto the shaft in re.

ticularly in Figure 4 of the drawings the peripheral contour of the camis determined to effect a swinging movement of the arms 62 downwardlyand upwardly throughout one complete revolution of the cam. Moreparticularly it will be noted that the peripheral surface of the cam 65which effects downward swinging movement of the arms 62 is indicated inFigure 14 of the drawings by the numeral 14, and this surface is of acontour to maintain the arms 62 in their lowermost positions for aperiod of time sulficient only to enable the slide 5! to advance theglass panel 5| out of engagement with the arms 62.

The shaft 65 is journalled in a part of the machine frame 59 below thefixture 55, and is connected to a drive shaft shown in Figure 4 of thedrawings. is secured to the shaft 55 and is connected to a sprocketwheel 11 by a chain 18. The sprocket wheel H is secured to a transverseshaft 79 shown in Figure 22 of the drawings as journalled on the machineframe and as having a gear 80 secured thereto adjacent the sprocketwheel 11. Referring again to Figure 4 of the drawings, it will be notedthat the gear 80 meshes with an intermediate gear B| suitably journalledon the machine frame 59 in a position to mesh with a pinion 82, which inturn, is secured to the drive shaft I5. Thus the cam shaft 66 as well asthe shaft 19 is rotated by the drive shaft 15.

Glass panel operating slide The glass panel operating slide 51 is shownin Figures 7 to 12 inclusive. The slide 51 is supported on the machineframe 59 below the fixture 55, and the purpose of this slide is todisengage the glass panel 5| from the fixture 56 in the lowermostposition of the arms 52, and to also advance the panel 5| toward theframe holding fixture 58. In detail the slide 51 embodies a supportcomprising laterally spaced rails 84 suitably secured to the main frame55 and extending f beneath the shaft 60. Sliolably supported on the topsurfaces of the rails 84 is a block 85 having a longitudinally extendingkey 85 secured to the bottom face thereof and extending between therails 84 to hold the block 85 against lateral shifting movement relativeto the rails.

Supported on the top surface of the block 85 adjacent the rear endthereof is a plate 81 having strips 88 suitably secured to oppositelongitudinal edges thereof and projecting downwardly along oppositesides of the block 85. As shown particularly in Figure 9 of the drawingsthe lower ends of the strips 88 are formed with laterally inwardlyextending ribs 39, and these ribs respectively slidably engage inelongated grooves 96 formed in opposite sides of the block 85. Thearrangement is such that the plate 31 may be moved longitudinally of theblock 85, and the purpose of this movement will be presently described.

Positioned on the block 85 at the front end of the plate 81 isa secondplate 5| having the cen 9| in a horizontal'plane relative to the block85.

The plate BI is arcuatein shape at the rear end,

and has a bearing engagement with a corre-T spondinglycurved surface atthe front end of the plate 81..-.As shown particularly. inFigure 7" .0fthe drawingsa lug 55 -projects rearwardly'z:

In detail a sprocket wheel 16 from the arcuate surface of the plate BIand extends into a recess -84 formed in the plate '81.. The oppositesides of the lug 93 are respectively engaged by set screws 95 threadablyengaging the plate 87 and having the head portions accessible throughopenings in the strips -88. The arrangement is such that by relativelyrota-ting the set screws 95, it is possible to angularly adjust the.plate 9| relative to the block 85 and the purpose of this adjustmentwill also be presently described.

The front face 95 of the plate BI is normal to the path of slidingmovement and forms a bearing for a bumper bar 97. The bumper bar 97comprises a member 98 extending in the direction of length of the face99 on the plate '9I and secured to the latter by "screws 99. Referringagain to Figure "7 of the drawings, it will be noted that the screws 99extend rearwardly through transversely elongated slots I89 formed in thefront side of the plate SI and respectively threadably engage plungersIill. The plungers IIII are respectively freely slidably supported inbores I02 formed in the plate 9! at opposite side edges of the latterand having their axes extending parallel to the face 95 on the plate9'I. The arrangement is such as to enable limited sliding movement ofthe bumper bar 97 along the face 95 of the plate 9i, and the purpose ofthis sliding movement will become more apparent as this descriptionproceeds. It will further be noted from Figure? of the drawings thatsliding movement of the bumper bar 97 relative to the plate 9| in thedirection of the arrow Iil3 is resisted by a coil spring I04 supportedin the lowermost bore I02 shown in Figure '7 and enga'geable with theadjacent plunger IIII.

Projecting forwardly from the bumper bar 97 on the slide 57 is a pair oflaterally spaced arms I 05 and I136. The arms are spaced laterally fromeach other and have rests I 07 suitably secured to the top surfacesthereof. The rests I87 serve to engage the underside of the glass panel5! when the latter is lowered by the fixture 56. It will be noted fromFigure 1 of the drawings that the arm I05 is of greater length than thearm I96, and serves to support the lower edge portion of the glass panel5I at points adjacent the front and rear edges of the panel. As shown inFigure of the drawings, the rear ends of the arms I05 and me arerespectively supported in recesses formed in the top surface of theblock 85 at opposite sides of the latter, and are secured to the block-85 by fastener elements I68. Thus the arms I05 and I06 move as a unitwith the slide block 85.

At the start of the cycle of operation of the apparatus the slide 57 islocated in its rearwardmost position shown in Figures 1, 5 and 6 of thedrawings. This position is so determined with respect to the fixture 55that when the latter is operated to swing the arms 62 downwardly theglass panel 5I is deposited on the rests I07 with the rear edge of thepanel 5I immediately adjacent the bumper bar 97. In order to assureproper location of the bumper bar 97 with respect to the rear edge ofthe glass panel 5I, provision is made for adjusting the plate 9|relative to the slide block 85. This adjustment is accomplished by ascrew I09 threadably engaging a. block III), which in turn is secured tothe slide block 85 beyond the rear edge of the plate 87. As shown inFigure '7 of the drawings the front end of the screw I09 engages therearedge of the plate 87, and rotation of this screw relative to the blockIII) serves to move the bumper bar 97 on the plate 9-I forwardly orrearwardly depending on the direction of rotation of the screw I09. Alsoit is important to locate the bumper bar 97 in parallel relationship tothe rear edge of the glass panel 5I., and this may be accomplished byadjusting the screws to rotate the plate 91 about the fastener 92.

By reason of the foregoing the bumper bar 97 is in a position toimmediately engage the rear edge of the glass panel 5| upon forwardmovement of the slide 57. In this connection it is pointed out that astrip III of resilient material may be secured to the front face of themember 98 to avoid chipping or breaking the glass panel by the bumperbar 97. As the slide 57 is moved forwardly to advance the glass panel 5Iin a direction toward the frame holding fixture 53, the bottom edge ofthe panel is shifted laterally to assure aligning the same with thebottom bar 53 of the frame, and this is accomplished by shifting thebumper bar 97 in the direction of the arrow Hi3 against the action ofthe spring I64. Referring again to Figure 7 of the drawings, it will benoted that a lug H2 is secured to the underside of the bumper bar 97intermediate the ends of the latter, and projects in a forward directionfrom the bumper bar. The lug I I2 has a cam face H3 at one edge forengagement with a projection II l on the machine frame. As shown inFigure 1 of the drawings the projection lid is positioned immediatelyadjacent the rear side of the frame holding fixture 58, and coacts withthe cam face II3 to urge the bottom edge of the glass pane1 5I againstthe bottom bar 5-3 of the frame 5% which is supported on the fixture 58.

The slide 57 is operated by mechanism shown best in Figure 5 of thedrawings. This mechanism embodies a crank arm II5 secured to the shaft79 and having a pin IIB projecting laterally from the free end thereof.The pin H6 is pivotally connected to one end of a link H7, and theopposite end of the link is connected to a lever II8 intermediate theends thereof. The upper end of the lever IIB extends into a recess II9formed in the rear end of the block 85, and is pivoted to the latter bya pin I 20. The lower end of the lever H9 is pivotally connected to themachine frame by a shock absorbing connection I2I which will bepresently described. The above construction is such that rotation of thecrank I I5 from the position thereof shown in Figure 5 of the drawings,and throughout of travel moves the slide 57 from its inoperativeposition adjacent the rear end of the machine to its forwardmostposition wherein the glass panel occupies its final position in theframe 50. In fact the parts are so designed that the glass panel 5| isset in the frame 50 just before the crank approaches the end of itstravel.

The shock absorbing connection I2I serves to enable continued movementof the crank II5 without jamming the parts or injuring the glass I panel5I. As shown in Figure 40 of the drawings, the shock absorbingconnection I2I comprises a rearwardly opening U-shap'ed bracket I22having the extremities of the arms I23 suitably pivoted to the machineframe 59. Supported between the arms I23 for movement toward and awayfrom the base portion I24 of the bracket I2I is a plate I25 having meanslidably supporting pins I26. The pins 128 are also slidably-supportedin openings formed in the base I24. and.
